# Retire credits

> How buyers can retire credits to meet climate targets, make environmental claims, or meet regulatory requirements with immutable retirement certificates

Buyers can retire credits in order to meet corporate climate targets, make a public environmental claim or meet government or regulatory requirements.

Credits can be retired either in the buyer's name or in the name of a beneficiary, for example when credits have been purchased by a marketplace or intermediary on behalf of their customer.

<Warning>
  After retiring credits, the credits become immutable and can no longer be transferred or altered.
</Warning>
